1. A ground penetrating radar for detecting objects comprising:

  • signal generation means for (i) generating and transmitting a stepped frequency master signal and (ii) generating a tracking signal offset in frequency from the master signal by an intermediate frequency;

    return signal processing means for (i) receiving a return signal reflected from the ground region and (ii) processing the return signal using the tracking signal and the master signal to determine amplitude values and phase values indicative of target matter;

    gating means for (i) pulsing the master signal and (ii) gating the return signal; and

    antenna means for (i) coupling the master signal into the ground and (ii) coupling a reflected signal from the ground.
